Abstract: A system and method for determining the characteristics of a device coupled to a client device are disclosed. A method, according to one embodiment, includes driving a display device with a first video output signal formatted according to a first video interface specification; responsive to driving the display device, soliciting user input based on information included in the first video output signal; determining a characteristic of the display device based on the user input; and driving the display device according to the determined characteristic.

Abstract: A scanner phase control for a scrolling color projector utilizes the back-EMF value of a motor which rotates a prism of the scanner to set a reference point for the prism. A reference phase signal is provided which corresponds to timing information of the scan of a stripe of light provided by the prism. The phase of the motor is altered in response to the reference phase signal such that the back-EMF zero crossings of the motor coincide with the beginning of a scan as identified by the reference phase signal.

Abstract: An imaging system using an area sensor in which reading of very fine object such as a manuscript, etc. is permitted to be carried out. This imaging system includes an area sensor in which a plurality of pixels are two-dimensionally arranged so that a pixel pitch in an X direction is an integer multiple A of a pixel width and a pixel pitch in a Y direction is an integer multiple B of a pixel length; object driving means for moving an object by the pixel width/length so that in a condition where one of the pixels corresponds to a part of an object, an image of a unit of 1/AB of the part of the object is formed on one of the pixels; and photoelectric conversion control means for allowing the area sensor to carry out photoelectric conversion in a manner synchronized with movement of the object.

Abstract: A color projection video system utilizing only a single light valve. A white light source is separated into into red, green and blue bands. Scanning optics cause the RGB bands to be sequentially scanned across a light valve, such as a transmission LCD panel. Prior to each color passing over a given row of panels on the light valve, that row will be addressed, by the display electronics with the appropriate color content of that portion of the image which is being displayed. The image is projected by a projection lens onto a viewing surface, such as a screen. The device includes circuitry to synchronize the illumination of the light valve with the video signal and to minimize video breakup when changing video sources.

Abstract: A circuit for varying the strobe timing of the PIP in a VTR which includes a microcomputer, first, second and third counters receiving the signal for varying the strobe timing of the microcomputer, a modulo-4 counter and logic receiving the output of the first counter, a decoder receiving the outputs of the second and third counters, a multiplexer receiving the output of the decoder, the output of the decoder being applied to the clear terminal of the second counter, a register receiving the output of the multiplexer, and a memory connected with the register. The vertical synchronizing pulse of the sub-screens is applied to the clock terminals of the first and second counters and the clock terminal of the register. The output of the microcomputer is applied to the clock terminal of the third counter.
